Bruce Jenner's ex-wife, children and stepchildren took to Twitter late Friday to voice their support of his decision to live his life as a transgender woman.

"Not only was I able to call him my husband for 25 years and father of my children, I am now able to call him my hero," Kris Jenner posted on Twitter, shortly after Bruce Jenner's "20/20" interview with Diane Sawyer aired.

"Love is the courage to live the truest, best version of yourself. Bruce is love. I love you Bruce. #ProudDaughter," Kim Kardashian tweeted. "Your honesty has opened the doors for others to be courageous and live an authentic life! #respect #hero #family."

"Woke up still in awe... I've never been more proud of you, Dad!!!!!!" Kylie Jenner said.

"You have always been a role model to me and now more than ever, I look up to you. LOVE YOU" said Rob Kardashian.
